What is the correct hand to use when driving?

I bring it up because i was driving with my mom and im right handed but i drive with my left hand and my mom legit got mad at me “omg youre driving with your left! Youre right handed! Youre Supposed to drive with your dominant hand!” Like uhhh my left hand is my dominant driving hand? I use the right when the left gets tired but i drive better with the left. Idk if its a motorskill thing cause our wheels in the US is on the left side of the cab?
